You can by pass the level requirrement to enter a high level raid by letting a lvl 90 enter before you, you follow right after as he zones in. Congtrats, you are now here u should not be able to be.

Will highlight what Aelo said here; he has a bit more understanding about this bug related to 80 soloing with pallys

It was reported over 3 months ago by Splosion (the 80 Pally who discovered it and solo'ed LK25H) but nothing was done about it. Hopefully now that a current-tier raid boss has been killed, Blizzard will jump into action and finally fix it.

Edit: I have made a thread on the offical Forums aswell, with the hope that blizzard might fix this

It is possible since they removed the "raidgroup recuirement" in 5.1 i think
Aelobin is clearing DS HC with his guild on lvl 80... 7/8 down... you can watch this on youtube

But most dungeons and raids also have a level restriction, don't they? As in they'll give you a "You must be x level to enter this dungeon" error. I know they used to, that might have changed. Either way, apparently it's legit according to the armoury...which is pretty impressive :O

Some of the MoP BoE blues and greens can be used by level 80s, and because of how the stats work out, 80s with blue/green MoP gear have a nearly 100% parry/dodge chance from bosses, and vengeance can hit for absolutely insane numbers.

People if you have no idea what you're talking about atleast do some research before saying something...
Level 80s CAN enter Mogu'shan Vaults, just like they can enter any other raid in the game.When patch 5.1 came out, it removed the level requirements for every single raid, no one is sure if it was intended seeing as it has not been hotfixed yet or just a weird bug which cannot be fixed easily.
How has he done it? MoP Greens/blues in combination of Cata dungeon blues and ICC 25 HC pieces, the mastery,dodge,parry and so on stack way too well with those items on level 80 allowing them to parry every single attack from most bosses, however they would still gain Vengeance and since the bosses hit them for shit tons they will get shit tons of AP from vengeance causing them to do shit tons of damage them self... This is the exact same way of how that blood DK solo'd Baleroc 25 heroic as a level 80 and Protection Paladin soloing LK 25 hc as level 80 aswell.
Is it hard to do this? No. Is it impossible? No. Does it take time to get that gear? Not really, not unless you're really poor or your server is super dead.
Don't believe me about this? Okay well here's his armory then,look at his MGV progress http://eu.battle.net/wow/en/characte...t/Faruz/simple

I'ts not really clear if It's a bug or a feature that you can enter High level instances. But the truth is that it is possible.
